Top lane

In top lane use your ablities to farm,and use your passive to harass and push back the opponent.
Your "e" (bola strike) is a very good harass. Make sure to pay attention for ganks or they could shut you down. Once your jungler comes to gank,go into the bush and wait. When the time comes jump and use your bola strike (e) and your other ablities. Remember that you are top lane and you are an important role for your team.

Ferocity/Abilities

You have ferocity that builds every time you use an ability on an enemy. Build your ferocity to 4 because after you use an ability when you are at 4 ferocity you reach 5 ferocity which will refresh the cooldowns on your q,w,e, so you can do any ability 2 times instead of 1. To poke use your "q" Savagery. For sustain use your "w" Battle roar to heal. Use your "e" to harass and slow enemies.
When you attack and enemy champion make sure ferocity is 4. I recommend using this combo: Q 2 times,
e,w,then back off. Note that you must pay attention to your health to see if you are ready to attack.
Your ultimate, Thrill of the Hunt will reveal all champions in the fog of war in a radius around you.
(Also stealthed champs) You will passively gain Ferocity and your passive will be applied. But.once you attack or use an ability your ult will end.

Teamfights

In teamfights you always want to focus down high priority targets like mages or adc's,then move on to other targets. Try to have teamfights on open areas so you can use your "r" then perform the combo in chapter 2. to get away use your "r". Make sure that the enemy team doesn't have anyone that can reveal you during your ulti or you could be focused very easily. Examples: Tf,Lee Sin,and anyone with oracles.
